source: palm/trunk/SOURCE/cpulog_mod.f90 @ 4548

Last change on this file since 4548 was 4539, checked in by raasch, 5 years ago
checks added, if index limits in header are exceeded (restart_data_mpi_io_mod), bugfix in rrd_mpi_io_int_2d, location and log_point names added/modified, cpu time per grid point and timestep does not included initialization and spinup any more (cpulog_mod)

[1]	57	! Description:
	58	! ------------
[1682]	59	!> CPU-time measurements for any program part whatever. Results of the
	60	!> measurements are output at the end of the run in local file CPU_MEASURES.
	61	!>
	62	!> To measure the CPU-time (better to say the wallclock time) of a specific code
	63	!> segment, two calls of cpu_log have to be used as brackets in front and at the
	64	!> end of the segment:
	65	!>
	66	!> CALL cpu_log( log_point(n), 'any identifier', 'start' )
	67	!> ... code segment ...
	68	!> CALL cpu_log( log_point(n), 'any identifier', 'stop' )
	69	!>
	70	!> Parts of the code segment can be excluded from the measurement by additional
	71	!> call of cpu_log:
	72	!>
	73	!> ... first segment to be measured
	74	!> CALL cpu_log( log_point(n), 'any identifier', 'pause' )
	75	!> ... oart of segment to be excluded from measurement
	76	!> CALL cpu_log( log_point(n), 'any identifier', 'continue' )
	77	!> ... second segment to be mesasured
	78	!>
	79	!> n is an INTEGER within the interval [1,100] defining the id of the specific
	80	!> code segment, 'any identifier' is a string describing the code segment to be
	81	!> measured. It can be freely chosen and results will appear under this name in
	82	!> file CPU_MEASURES. ids can only be used once. If you like to do a
	83	!> measurement of a new part of the code, please look for an id which is unused
	84	!> ao far.
	85	!>
[2932]	86	!> runtime_parameters-parameter cpu_log_barrierwait can be used to set an MPI
	87	!> barrier at the beginning of the measurement (modus 'start' or 'continue'),
	88	!> to avoid that idle times (due to MPI calls in the code segment, which are
[1682]	89	!> waiting for other processes to be finished) affect the measurements.
	90	!> If barriers shall not be used at all, a fourth, optional parameter has to be
	91	!> given:
	92	!>
	93	!> CALL cpu_log( ..., ..., 'start', cpu_log_nowait )
	94	!>
	95	!> Variable log_point should be used for non-overlapping code segments, and they
	96	!> should sum up to the total cpu-time required by the complete run.
	97	!> Variable log_point_s can be used for any other special (s) measurements.
